LOCK.

Patented Oct. 30, 1906.

To all whom it may concern:

Be it known that I, HORACE D. OHIPMA a citizen .of the United States, residing at Home City, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Locks, of which the following is .a specification.

My invention rel ates to a permutation-lo ck.

The object of my invention is to provide a simple and efficient lock with the least possible parts and those parts structurally simple and adapted to fit compactly in thecasing. Another object of the invention is to providea lockof the class in which no indicating figures are employed on the face of the lock, the indicating being .of the click variety.

The features of my invention are more fully set forth in the description of the accomp anying drawings, forming a partof this specification, in which Figure 1 is a plan view of the lock with the back plate removed, showing the bolt in locked position and its contained actuating mechanism in normal position. Fig. 2 is a of the indicator-lever.

similar view to thatof Fig. 1, but showing the bolt in its unlocked position.

Fig. 3 is a detailed plan view of the cam-plate in normal position. Fig. 4 is a similar view to that of Fig. 3, showing the cam-plate in partial actuating position. Fig. 5 is a perspective view of the cam-plate. Fig. 6 is a sectional view on line mm, Fig. 4,. Fig. 7 is a detailed view Fig. 8 is a plan view of one of the tumbler-plates. Fig. 9 is a perspective view .of one of the actuating-plates between the tumbler-plates. Fig. 10 is a detailed view of the preferred form of locking mechanism for the bolt.

A represents the supporting-plate; B, the tumbler-shaft journaled therein; B, a shell on the front end of the shaft adapted to be secured to thedoor, and B the knob for ma nipulating the tumbler-shaft. (See Fig. 6.)

a b c d represent tumblers journaled on sleeve 6, fixed to plate A, within which sleeve the tumbler-shaft journals.

Between each .of the tumblers a transmission-plate 9, provided with the down wardlydepending lug h. (See Fig. 9.) E represents an indicating-diskadapted to en: gage the first .of the series of tumblers. Plate E is provided with ,a I series of peripheral notches against which the indicating-leverC tangentially bears. Thus far the construc-' .tionis substantially the same as that shown in Patent No. 590,131, granted to meSeptember 14, 1897.

Sleeve e is provided with the flange l, rigidly attached to plate A. The periphery of .onehalf of said flange describes a circle Yon sleeve e as a center, the other half of the periphery of said flange being cut away, and from this cut-away portion of the periphery there proj ects a lug 2, equal in length to the full radius of the flange. (See Figs. 3, 41, and .6.) F represents a cam plate provided with an orifice 3 of a diameter equal to the full .diameterof the flange 1 and lug'2, said orifice having a peripheral notch 4, adapted to be .engaged by the lug 2. (See Fig. 5.) Plate F is placed on flange 1 as a bearing; but when-- notch 4 is opposite to lug 2 a spring (to be later described) presses plate F in a radial direction to engage said lug and notch, and thus lock plate F against rotation. The tumblers a b c d are provided with notches 5. 8.) Plate F is provided with a radial projection 6, the inner end of which overhangs the peripheries of said tumblers and the outer end of which projection is adaptedto engage and throw the bolt. When these tumblers and notches 5 are alined by Working the combination, mechanism is provided which throws the plate F laterally, so that the inner end of projection 6 falls into said alined notches and fixes plate F or connects it rotatively with the tumblers and tumbler-shaft, so that by rotating the tumbler-shaft in this position the bolt can be shot The mechanism for thus shifting plate F is as follows:

7 represents a stud-shaft'secured to frame A upon one side of the tumbler mechanism, (see Fig. 3,) upon which shaft'is pivoted a (SeeFig.

spring-actuated depressing-finger 8, receiving tension from spring 9. In the normal position of plate F finger 8 bears against the outer edge of projection 6 .and exerts aconso as to secure y interlock the tumb ers with projection 6 for the unlocking movement, which is in the left-handdirectiono'f rotation. The left-hand walls of notches 5 are inclined outwardly, so that in the locking movement j ing the lever toward plate E.

the tumblers will be disengaged from their interlocking relation with the imier edge of projection 6 at the time the outer edge of projection 6 is brought to rest against the notched end of finger 8 in the position indicated in Fig. 3, the plate F being again shifted on its bearings to interlock lug 2 with the notch 4, and the tumblers can then be freely manipulated independent of the eam-plate F.

' 10 represents a segmental guide attached to plate A. (See Figs. 3 and 4.) It is curved in the arc of movement of projection 6. Projection 6 is notched out on its side adj aeent to guide 10. In normal or locked position with lug 2 engaged into notch 4 the unnotched portion of the edge of projection 6 abuts against the right-hand end of guide 10, as shown in Fig. 3, holding plate F against rotation. When the combination is worked and projection 6 .drops into the alined notches 5, the notched portion of projection 6 is brought in line concentrically with guide 10, so that in the locking and unlocking movement projection 6 moves in its are of travel on the guideway formed by the rib 10.

C represents an indicator-lever pivoted on stud 7, having a spring 12 for normally press- 13 represents a roller pivoted to the free end of lever C and engaging the notches in the indicating-disk E.

It is desirable to throw out lever C during the unlocking movement, and to accomplish this plate F is provided with a cam-like projection 14, adapted to engage the downwardly-extending stem 15 on the free end of lever C (see Fig. 7) to throw out lever C at the proper time, disengaging the roller 13 from the notches of the indieating-disks E. 16 represents the sliding bolt sup orted by frame A. It is provided with stopugs 17 18 for limiting its movements. It is also provided with notch 19, into which the outer edge of projection 6 engages for shifting the bolt when the combination has been worked and the inner end of projection 6 has dropped into the alined notches 5 of the tumblers.

In order to prevent the bolt from being actuated independent of the tumbler mechanism, I provide a guard-plate 20, pivotally supported upon frame A and having a downwardly-projecting lug adapted to be engaged into the notches 21 22, formed in the upper end of bolt 16 at positions corresponding to its limit of movements in opposite directions. 23 represents a spring for normally holding guard 20 in engaging position with the notch of bolt 16. The forward end of the guard 20 is made with an inclined edge, (see Figs. 1 and 2,) adapting the same to be readily engaged by the projection 6 for disengaging the guard from its interlocking relation with bolt 16. The forward end of bolt 16 is provided I with an extension 24 on its lower edge, provided with a notch 25, adapted to be engaged by the outer edge of projection 6 to form a supplemental lock against independent bolt manipulation.

From this description it will be seen that the bolt 16 cannot be shifted except by the engagement of projection 6 into notch 19 of bolts 16.

The operation of working the look through the operation of the tumbler mechanism will also be understood from the foregoing description.

There are many ways of changing the details of this lock without departing from the characteristic features of the invention; but a prominent feature of the invention is the plate F, formed with a projection, the inner edge of which is adapted to engage into the alined tumbler-notches and the outer edge of which projection is adapted to engage and shift the bolt through the manipulation of this tumblenshaft.
